LAMP-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 380,885, dated April 10, 1888.

Application filed February 18, 1887. Serial No. 228,135.

The object of my invention is to supply a 1 means of immediately and automatically extinguishing the flame of the lamp upon the tipping of the same.

In the accompanying drawings, Figure 1 is an isometric View of a lamp provided with my invention, the upper part of the lamp-burner,

the lampchimney, and the parts which constitute my invention being in central vertical section; Fig. 2, a plan of a lamp-burner provided with my improvement; Fig. 3, a central vertical section, on the line 00 0c in Fig. 2, of a lamp-burner provided with my improvement, the reservoir of the extinguisher being represented as filled with a liquid; Fig. 4., a section on the line was in Fig. 2, of a lampburner provided with my improvement, showing also the lamp-cone, also in central vertical section; Fig. at, an isometric sectional view of my invention detached.

Inmost cases where a fire is caused by the breaking of a lamp the lamp is tipped off from a table, bracket, or other support-that is, the lamp isinclined from its usual position before it is broken, as by striking on the floor or other surface-and the improvement hereinafter described is intended to extinguish the flame of the lamp as soon as thelamp is moved out of its vertical position.

In the drawings, the oil-reservoir A, the burner B, consisting of a screw-threaded body, I), adapted to be engaged with a screw on the oil-reservoir and supporting a wick-tube, b, a ventilationtube, b", a lamp-cone, b having a slit, 1), for thefiame, the wick-raising wheel b the perforated draft-plate b and the chimney 0, supported upon said draft-plate, are of any usual construction and need no further description.

(No model.)

To the lamp burner I apply a reservoir, D, adapted to contain water or other extinguishing or non-combustible fluid, F, said reservoir being held in place by arms or brackets d,v which extend from the lower part of the body of the burner B to the inside of the reservoir D, said reservoir being preferably of an annular shape, as represented, and entirely surrounding the wick-tube. From the top of the reservoir D extend pipes d to the wick-tube, one of said pipes being arranged on each side of said tube and being bent up in contact with said tube on one side of the same and in contact with the ventilation-tube on the other side of said wick-tube to about the top of said wicktube. The tubes (1 0r pipes serve, therefore, partly to support the reservoir D and to hold it in place. Between. the draft-plate and the reservoir D are interposed three or more brackets, E, four such brackets being shown in Fig. 5. These brackets steady the draftplate and keep the draft-plate and the reservoir D in their proper relative positions.

It is evident that if the reservoir D and its pipes d be tipped very slightly the water-will flow out of the pipes over the top of the wicktube 2) and immediately extinguish the flame of the lamp before the lamp will have time to reach the floor and be broken. The upper ends of the pipes which discharge the water from the reservoir D are preferably covered with wire-gauze, d, to break up the stream of water issuing from said pipes and to cause it to be discharged over the entire width of the top of the wick equally. The reservoir D may readily be filled through one of the dischargepipes after removing the gauze therefrom.

I do not limit myself to the shape of the reservoir or to the exact location shown, it being desirable, however, that the water or other flame-extinguishing liquid should reach nearly to the top of the discharge-pipes when the lamp is in a vertical position, and it is there fore preferable that the water-reservoir should be arranged above the oil-reservoir. The exthe substitution of new lamps for those now in use.

The use of the improvement above described would in many instances prevent the serious conflagrations which follow the overturning and breaking of kerosene-lamps and the consequent loss of life and property, and would prevent railway-car lamps from setting the cars on fire when the latter are derailed and overturned.

I claim as my invention 1. In combination with a wick-tube of a lamp-burner, a reservoir detachably attached to and supported by said lamp-burner, and adapted to contain a flame-extinguishing fluid, and provided with one or more dischargepipes arranged to-discharge the contents of said reservoir over the top of said wick-tube when said wick-tube and reservoir are inclined or overturned, as and for the purpose specified.

2. The combination of a lampbnrner provided withawiek tube,andareservoirarranged around said burner and detachably attached thereto and supported thereon and provided with discharge-pipes leading from said reservoir to the top of said wick-tube, said reservoir being adapted to contain a flame extinguishing fluid, and upon the overturning of said lamp-burner or the inclining of the reservoir to discharge said fluid through said discharge-pipes at the top of said wick-tube, as and for the purpose specified.

3. The combination of a lamp-burner provided with a wick-tube and with a draft-plate, the annular reservoir provided with dischargepipes arranged on opposite sides of said wicktube, and brackets or arms arranged between said draft-plate and said reservoir, as and for the purpose specified.

4. The combination of a lampburner provided with a wick-tube and with a draft-plate, the annular reservoir provided with dischargepipes arranged on opposite sides of said wicktube, the discharge ends of said discharge pipes being covered with wire-gauze and brackets or arms arranged between said draft-plate and said reservoir,as and for the purpose specified.

In witness whereof I have signed this specification, this 14th day of February, A. D. 1887, in the presence of two subscribing witnesses.
